I'm hitting a problem with the native AVF driver. The issue does not seem to exist when using the DPDK driver. This is on stable/2009, with the DPDK bump to 2008 reverted (b/c 2008 doesn't work with mellanox anymore apparently).
I have an x710 card configured with a 4x10G breakout cable. The code that is
failing is
if ((ad->feature_bitmap & VIRTCHNL_VF_OFFLOAD_RSS_PF) &&
(error = avf_op_config_rss_lut (vm, ad)))
return error;
Here's the debug log:

If I comment out the 2 calls to VIRTCHNL_CF_OFFLOAD_RSS_PF, the device
initializes.
Is there something about the breakout cable configuration that needs special
attention from this code?
Thanks,
Chris.
